PARACHUTE.

Application filed February 25, 1927. Serial No. 170,957.

This invention relates generally to safety devices for flying machines, and has more 'particular reference to a novel type of parachute. This application is a continuation in part of an application filed by me on May 29, 1925, Serial Number 33,598.

The invention has for an object the proviy sion of an improved parachute which will act efliciently, and which is normally protected against exterior influences of weather conditions.

For further comprehension of the ,invention, and of the objects and advantages thereof, reference will be had to the fellowing description and accom anying drawings, and .to the ap ended claims in which the various novel eatures of the invention are more-particularl set forth.

Fig. 5 is a detail edge view of one of the wings o f thm-device with the wing members thereof in unfolded, or extended position, as seen in the direction of the arrows 5-5 of Fig. 6.

. Fig. 6 is a side elevation of the parachute in completely opened, position, descending and free from the flying machine.

Fi 7 is a horizontal sectional view taken on th line 7-7 of Fig. 6. Fig. 8 is a side elevational view of a flying machiiie equipped with the invention para-- .'chute.

The reference numeral 10 indicates generally aying machine, having Aposts 11 projecting from y, the bottom thereof and connected to the side of a cone member 12. Pivoted as at 13 to the inner side of the 50 bottom of the cone member 12 are levers 14 having projecting tongues 15. A disc 16 i s housed in the cone member. 12 and has a central projecting rod 17 slidable in an aperture 18 in the cone member. A spring 19 urges the rod 17 and disc 16 outwards.

' Referring to t e drawings forming a Ina-f Another rod 2O of disc 16. v

A gondola 21 has a door 22` and atop flange 23. Hingedly connected as at 24 to the top flange 23 are the center wing menibers 25 and 26 of a pair of Wings, completed by end wing members 27, 27 and 28, 2S hingedly connected as at 29 to the center wing members 25 and 26 respectively. 4Springs 30 are coaxially mounted ou th(l hinges 29, and act between the center wing Lmember vand the end wing members, urging the end wfng members into the position shown in Figs. 5, 6, and 7, further opening 'of the wings being arrested by stops 31.

The center wing members 25 are formed with top flanges 32, and the end wing members are shorter than the center wing members so that a groove 33 exists when the end wing members are folded upon the center wing members as shown in Figs'. 1 to 4. The tongues 15 of the levers 14 are engageable in'- thisV groove. Co-axial with the hinges 24 are extension rods 34 with springs 35 thereon, normally urging the wings downward to positions shown in Figs.6 and 7, and to lock the wings in this position, catches 36 on the flange 23 are engageable with complementary catches 37 on the center' wing members 25, 26. A parachute sail 38 is attached to the gondola 21 by ropes 39, for convenience shown broken on the drawin s glhe device is set in condition for operation by collapsing the parachute sail 38 as projects from the other side shown in Fig. 2, folding the end wing members against the` center wing members as shown in Fig. 3 against the unfolding action of springs 30, forcing the thus folded wings together against the'action of springs 35, en aging thetongue'l in the groove 33, an thereupon spring 19 forces the disc 16 between the backs ofthe levers 14. locking the folded wings to the cone shaped member 12, incidentally, the wings cannot open since they are locked by the levers 14.

VThe doorway 22 of the gondola 21'is placed f in a position so as to be.readily useable by occupants of the flying machine 10. The flying machine may now hop off on its journey. If an emergency arises and the occupants of the ying machine desire to leave the same, they enter the gondola 21 through the door-22v closing thedoor after them. Thereafter, they press agaln'st the rod 20, moving the disc 16 from behind the levers 1&1, against the action of spring 19, that is, the disc is moved from the position shown in Fig. 1 to the position shown in Fig. 2. Springs act to open the Wings,

members from against the center Wing members to a position as shown in Figs. 5 to 7.

Simultaneously, the springs 35 continue to act until the Wings are entirely open, vthat is till the catches 36, 37 engage each other, locking the wings in their open condition. The relatively uprushing air opens the parachute sail 88, and the falling parachute descends slowly and safely. In this condition the Wines aid in a slow descent of the parachute. dln the original condition, that is when the parachute was attached to the liying machine, the Wings shielded the parachute sail from Weather strains.

While I have illustrated and described my invention with some degree of particularity. I realize that in practice various alterations therein may be made. I `therefore reserve the right and rivilege of changing the form of the details of construction or other- ,to the flying machine, a gondola, centralv Wise altering the arrangement of the correlated parts without departing from the spirit or the scope of the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is 1. A parachute with associated holding and releasing means for' a, flying machine, comprising a cone shaped member secured Wing members hingedly attached thereto, end Wngmembers hingedly attached to the central wing members, the end Wing members being foldable against the central Wing members, means for normally urging the end wingmembers toopen position, means for normally urging the central wing menibers toopen position, means for releasably securing the end and central wings in closed position to the cone shaped member, and a collapsed parachute sail attached to the gondola, and housed Within the folded Wings.

2. A parachute with associated holding and vreleasing means for a flying machine, comprising a cone shaped member secured to the flying machine, a gondola, central Wing members hingedly attached thereto, end Wing members hingedly attached to the central Wing members, the' end Wing members being foldable against the central Win members, means for normally urging the en wing members to open position, means for normally urging the central Wing members to open position, a latch secured to the gondola, a complementary latch secured to the central win and eneageable with eaclr other to hol the centra )wing in open position, means for releasably securing'the end and central Wings in closed position tothe cone shaped member, and a collapsed parachute sail attached to the gondola, qand housed Within the folded Wings.

3. A parachute with associated holding and releasing means for a flying machine,

comprising a cone shaped member secured to the flying machine, a gondola,l central Wmg members hingedly attached thereto,I

end wing members hingedly attached to the central wing members, the end wing members being oldable gainst the central win"y members, means -for normally urging the en( wlng members to open posltlon, means for normally urging the central wing members to open position, means ,for releasably securing the end and central Wings in closed position to the. cone sha ed member, said latter means consisting o levers pivoted to the cone shaped member, means for engaging the levers to the Wings in a certainpositio'n of the levers, a disc slidably mounted inthe cone shaped member, afspring ur ing. the

certain dise to lock Nthe levers in the sai position, and a'rod attached to the` disc for manually moving the disc from the locking position, and a colla sed parachute sail attached to the gondo a, and housed within the folded Wings. f

In 'testimony whereof I have aiiizred my signature.
